Abstract
We have developed a method to characterize the stability of air textured yams with repeated load testing using an Instron tensile tester. We compare the instability values obtained with other methods with those using this method. We also assess the influence of process variables such as overfeed, air pressure, dry and wet texturing, and heat stabilization on the structural integrity of air textured yams with the different methods. We have observed that the test method that uses recovery from a given load as a criterion for yarn instability provides a more realistic assessment of structural integrity than the method that uses an extension percentage at a given load.
